Crews are working to repair and replace damaged concrete before grinding the roadway smooth. Until grinding begins, portions of the road could feel bumpy to those traveling through the area.

Overview

The pavement on this 15-mile stretch of eastbound I-90 between Issaquah and North Bend is more than 40 years old. With the approximately 73,000 vehicles using this portion of the major east-west corridor each day, the aging concrete is cracked and in need of repair.

Beginning in spring 2018, WSDOT contractor crews will repair and replace broken concrete panels, grind the top layer of pavement in all lanes to elimanate ruts and repave the outside shoulder, along with 10 off- and on-ramps. They will also overlay the eastbound I-90 Winery Road Bridge and westbound I-90 Raging River Bridge with new concrete. This two-year project is scheduled to be complete in fall 2019.

What should travelers expect?

Up to three lanes closed during the overnight hours.

Overnight off- and on-ramp closures.

Around-the-clock shoulder closures.

Single and double lane closures during the day.

Speed limit reduced to 55 mph.

Needs & benefits

Safety: Eliminating ruts limits the opportunity for water to collect on the roadway, which can reduce traction for drivers.

Preservation/Economic: Replacing broken concrete panels, grinding to eliminate ruts and repaving ramps improves the driving surface and preserves the roadway for decades to come. This work also reduces the need for costly emergency repairs.
